Abstract: Techniques of content unification are disclosed. In some example embodiments, a computer-implemented method comprises: determining clusters based a comparison of a plurality of audio content using a first matching criteria, each cluster of the plurality of clusters comprising at least two audio content from the plurality of audio content; for each cluster of the plurality of clusters, determining a representative audio content for the cluster from the at least two audio content of the cluster; loading the corresponding representative audio content of each cluster into an index; matching the query audio content to one of the representative audio contents using a first matching criteria; determining the corresponding cluster of the matched representative audio content; and identifying a match between the query audio content and at least one of the audio content of the cluster of the matched representative audio content based on a comparison using a second matching criteria.

Abstract: A reconstruction process includes measuring structures formed on a substrate by a lithographic process, determining a reconstruction model for generating modeled patterns, computing and minimizing a multi-variable cost function including model errors. Errors induced by nuisance parameters are modeled based on statistical description of the nuisance parameters' behavior, described by probability density functions. From the statistical description model errors are calculated expressed in terms of average model errors and weighing matrices. These are used to modify the cost function so as to reduce the influence of the nuisance parameters in the reconstruction, without increasing the complexity of the reconstruction model. The nuisance parameters may be parameters of the modeled structure, and/or parameters of an inspection apparatus used in the reconstruction.

Abstract: The invention relates to a concentrate for a heat transfer medium for solar units, comprisinga) from 45 to 98% by weight of triethylene glycol and/or tetraethylene glycol,b) from 1 to 55% by weight of 1,2-propylene glycol and/or ethylene glycol, andc) from 1 to 6% by weight of corrosion inhibitors.The concentrate is used in admixture with water for heat transport in solar units.

Abstract: The invention relates to low-viscosity, aqueous coolant brines based on inhibited alkali metal acetates and/or formates having improved corrosion protection, wherein the coolant brines contain 0.2 to 5% by weight of alkali metal sulfites or pyrosulfites, in particular 1 to 2.5% by weight of these sulfites. The brines according to the invention furthermore contain 0.3 to 5% by weight of basic substances from the alkali metal carbonates, hydroxides, borates and phosphates group and also 0 to 0.3% by weight of alkali metal silicates and 0.02 to 0.2% by weight of stabilizers from the triazoles, benzimidazoles and/or mercaptothiazoles group. The novel coolant brines result in very low corrosion rates, in particular with steel and cast iron.
